Hello,
I just bought a l1511 2cyl with hydro mission for slashing,everything works well but after 10 minutes it makes a whining noise then stops driving,allow it to sit for ten minutes and away it goes for about 100 feet then stops driving.
I have drained the oil,cleaned the strainers replaced the spin on and put fresh kubota grade oil back in and over filled it a couple of ltrs and it still does the same thing.
I've pulled the pump out of the box and stripped it hoping for a blockage but everything "looks" ok other the some wear on the plates which pull the pistons out of the barrels but their not bad enough to stop it working plus I think it's more a hydraulic issue.
Would anyone have an idea what would be causing this?
The pump modal is, daikin sundstrand 1515-602D,02-7-01508.
Also which other kubota modals use this type of transmission?

Oil tank over serviced? Not familiar with the unit you are talking about. When the oil gets hot and expands it needs somewhere to go. It should overflow back to the tank. If it's too full it will back up and lock up the motor.
